Problems solved by technology
[0003] In view of the deficiencies in the prior art above, the purpose of the present invention is to propose a commercial vehicle clutch control cylinder, which solves the problem that the existing clutch booster cylinder adopts a split design, which has a high risk of oil and gas leakage, many small parts, and complicated assembly. The air pipe is prone to failure, and the connection between the piston and the push rod is complicated, which affects the durability

The invention discloses a commercial vehicle clutch control cylinder, which comprises a cylinder body, a front end cover assembly, a piston, a push rod, an exhaust pilot control valve group and an intake pilot control valve. Cavity and hydraulic chamber, the rear end is provided with oil inlet and outlet. The piston is arranged in the piston chamber, and its center protrudes backwards to form an extension part. The extension part has exhaust passages through the front and back. The rear end of the push rod is connected with the piston, and the front end extends to the outside of the cylinder body. The exhaust pilot control valve group is located on the rear side of the piston, which includes a hydraulic rod and an exhaust pilot control valve. The front end of the hydraulic rod is sleeved on the outside of the extension. On and off. There is an intake channel on the cylinder body, and the conduction and disconnection of the intake channel of the intake pilot control valve. The invention adopts the integrated design of the oil cylinder and the cylinder, which reduces the risk of leakage, reduces the number of small parts, shortens the assembly man-hour, reduces the risk of dust entering, and improves the durability of the product.
Description
Technical field [0001] The present invention relates to the field of vehicle braking control, in particular to a commercial vehicle clutch control cylinder for controlling auto clutch. Background technique [0002] Automotive braking system to use to achieve a pneumatic braking valve, pneumatic valve mounted on the vehicle chassis. There are a few automotive clutch booster cylinder braking system, currently existing multi-clutch booster using split cylinder (cylinder and cylinder) design, the need for additional seals, increasing the risk of oil leakage; cylinder and the cylinder requires additional screw connection, Once the bolts loose, it will lead to failure; the same time, the relatively complex structure of the pilot control, the risk of oil leakage large, dust in the air into the small pieces and more complex to assemble; clutch booster cylinder using an external exhaust pipe, prone to failure; using split cylinder design and the cylinder, the piston connected with the pus...
